https://devzone.nordicsemi.com/f/nordic-q-a/24088/uart-communication-errors-on-initializationHello, I&#39;m having a lot of trouble debugging some errors on UART. I&#39;m initializing the UART as follows: void uart_init() { ret_code_t err_code; const app_uart_comm_params_t comm_params = { UART_RX_PIN, UART_TX_PIN, 0, 0, APP_UART_FLOW_CONTROL_DISABLEDen-USTelligent Community 13Fri, 04 Aug 2017 12:05:23 GMThttps://devzone.nordicsemi.com/thread/94846?ContentTypeID=1Fri, 04 Aug 2017 12:05:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a824b92-d1e7-4d28-8676-0ef784768591Andy<p>I found the problem. One of the UART pins was floating due to a damaged board, I guess this caused some unwanted noise in the UART.</p><div style="clear:both;"></div>
